Specication of Letters Patent.

Patented Oct. 12, 1915.

Original application led June 10, 1905, Serial No. 264,610. Divided and this application led January 15,.

1914. Serial No. 812,269.

To all whom t may concern:

Be it known that I, CARL L. NELSON, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Cash-Register Intion include, among others which will appear below, the provision of an automatic drawer-operated machine with means for not only registering the amount of the purchase or transaction 1n such a manner as to show figures which can be read from both sides of the machine on account of transparent indicators, but also for presenting these figures in their normal position instead of that which is usually a feature of cash registers. All the patentable subject matter disclosed in this application is not claimed herein however, as this represents one division of the original application filed June 10, 1905, Serial No. 264,610 and is intended to embody claims only to the indicat- Another divisional application is also being filed in which it is intended to embody the claims to the drawer operating mechanism of the invention.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicatey corresponding parts in all the figures.

Of said drawings; Figure 1 is a perspective view of a cash register embodying the present improvements; Fig. 2 is a plan of the same with the covering frame removed;

Fig. 3 is an elevation ofthe right end of.

the machine without the cover. Fig. 4 is a; sectional view looking to the left. Fig. 41 is a detail top view of a part ofi the mechanism shown'in Fig. 4. Fig. 5 is a sectional view on the line 7--7 of Fig. 2. Fig. 5 is an enlarged detail of the drawer connections. Fig. 6 is a sectional view looking toward the left on a larger scale than Fig. 4, and with parts removed. Fig. '7 is a plan More specifically the objects of the invenof the table on which the machine is supported. Fig. 8 is a detail view of the indicator elevating bar spring.

The entire machine is mounted on a base 40 provided withla suitable top or table. The table is provided with a cover 42 (Fig. 1) which is removable from the table and supports the various parts of the frame or casing. The casing itself is shown as consisting of several parts forming ends 48, a

top 44, a front side 45, and a rear side 46.

One end 43 is provided with a removable panel 43a having a slot 43h for a purpose to be described. The top is provided with an extension 44a, having transparent walls and top 47. The `front may be made in several pieces and is provided with a slot 48 for viewing a counter, and with a second slot 49 for a printing lever. In the front of the machine is located a small casing 50, which can be readily removed, and which is provided with openings 51 and 52 in its front and end walls respectively. Within the oaslng are a pair of longitudinal side-walls 58 (Fig. 2) having numerous passages and openings for receiving the various parts of the mechanism, and for supporting them.

There are'several other details which constitute a part of the frame, and which will be referred to -in a description of the elements with which they are connected.

Dra-'wer operating mcchcmz'sm.-The base 40 is hollow (see Fig. 4) and is provided with a drawer 54 which is preferably provided with compartments 55, and has a plate 56 mounted at itsrear end. Above the drawer the table is provided with a plate 57 for supporting part of the operating mechanism for the drawer. Upon this plate is mounted a lever 58 (Fig. 7) the latter being pivoted to the plate by means of a pin 59. This lever is connected, by means of a chain 60 or other flexible connection passing around a pulley 61, with the drawer.

This chain is shown as being connected with a hook 62 mounted on a bracket 63 mounted upon the plate 56 (Fig. 5a). A spring 64 mounted on the plate 57 normally pulls the lever away from the pulley 61 and constantly exerts'a motive force for opening the drawerf `At the beginning of the motion of opening the drawer it is retarded by the bearing of a roller 65 on a short arm 66 of the lever 58 against a cam surface G7 on a lbar 68. The purpose of this is vto avoid the rapid motion which would `be given to the drawer by the motor spring 6 4, and to permit'the drawer to close with a sharp mo# tionat'the end of the stroke. The bar.68 is l. vconnected .(see Fig. 3) to a pair of slides 69 movable on the plate 57, and it is normally 'forced toward the roller 65 `by means of a motor spring 70, which although acting to produce motion in the same direction as the they areplacedf,4 and by a-projection 69u the rear,

(Fig. 7) moving in a slot 57.

The plate 57 is provided withl a rack 71 (Fig. 7)- along which the bracket 68 passes.`

In order to prevent the drawer from being partly opened or closed and the motion stopped without completingt', thisbracket is provided with a hanging pawl 72 (Fig. 5a). This pawl is pivoted at a point well above its center of gravity, and on the lower part is provided 'with twonotches 73 (Fig. 5) havingA oppositely extending teeth 74 below them. "As the pawl passes over the rack in either direction it ywill be .forced to the rear withv respect to the direction of motion, and one of the teeth 74 passing along the top of the rack will be at all times in a position to engage the rack and stop the drawer if it vis .attempted to move Ait in the other direction.

mitted to drop from it so that upon reversing the motion ofthe drawer the same'conditions are repeated. yThe plate 57 is provided with a slot 75 for receiving the pawll and the bracket 68. The bracket 63 is 'provided (Fig. 7) with a projection 76 extending to and a projectioni77 extending to the side and by which it is guided below the cover plate 57. It isalso provided lwith a cam surface 78 which projects through the slot 75 and engages certain mechanism which will be described below.I The plate 57 has a slot 57b through which the "projection, 77 can be inserted. The mechanism )ust above describedv is more clearly Ashown and, described in theA original application yhereinbefore referred to and reference may be had to the same for a more detailedshowing and description of the same.

From the construction so far described, it will be seenflthat the opening of the drawer by the operation of the 4spring 64 causes vthe bar 68 to move to' the front in Fig. 7 a cer tain distance, taking with it thev slides 69;

also that thel bracket 63 is simultaneously caused to move with the drawer throughout thelength ofthe slot 75, carrying with 1t the pawl 72, the latter passing over the rack 7l When'the end of thel rack is reached, however, the pawl is per-v .upon a and preventing the movement of the drawer It will also be seen that the drawer 1s compelled to start to open in the wrong direction.

can be forcedback against the resistance of the spring,- and at the end of thestroke itl -can easily be moved to' lts extreme position.

, Drawer locking amd releasing device-. -In closed position the drawer is intended-to be held by the operation of a pin 79 (Fig. 5)

passing through'a slot 80 in the table,\and normally dropping by gravity infront of a projection`81 on the drawer. This pro]ec tion has a slanting surface 82 at the rear in vorder to assist in forcing the pin up when the drawer is closed, and assure that it will reach the top of the incline and fall behind the projection. This pin therefore auto-l` maticallv locks the drawer in closed positionl when it is forced to the end of its stroked and it must be displaced before the drawer` can be opened. In order to accomplish this result the pin extends upwardly some distance from the top of the table, and is provided with a guide 83. It is also provided with a passage or notch'84 through which passes the end of a bar 85 (Fig. 5). This bar is provided with a slanting or cam sur,

' face 86, which upon being moved lto the rear will engage-the top of the slot 84 and lift the pin. For the purpose of moving this bar it is pivotally connected by a bolt or pin 87 with a bell crank 88, which is pivoted from one end frame 53 to the other. This bell-crank is duplicated .at the two ends of the'machine, the two parts of it being connected by an operating bar 90. This operatving bar` preferably extends across the front of `the machine so that it will be within easy reach of an operator at all times. Obviously the depression of the operating bar causes the reciprocation of the bar 85 Ito the rear,

shaft 89 passing through the machine and the engagement of the surface 86 with the pin 79 so as to raise the latter and allow the drawer to be opened by the mechanism described. i

Keys and key-locking' mechanism-On the shaft 89 are also pivoted several sets yof key-bars 91 (Fig. 5). Each key=baris normally held in elevated position against a rod 92 by-meansvof-a spring 93 connected with a bar 94 passing across the machine. Each key is also provided with -a projection 95 extending below and havinga tooth 96 upon one side -thereof thereby providing two spaces 97. On one arm of each bell crank 88 is slidingly mounted a cross-bar 98 which is adapted to enterl the spaces 97 and lock the keysin their raisedl or depressed position. This bar is normally forcedVv under tension by a spring 99 into said spaces, but

under certain conditions it is held away from the projection 95 by means of a bar 100 mounted upon each of the bell cranks. This bar is held inl a depression in the bell crank and is rigidly connected with the bar 98 so that it prevents the latter from yielding to the spring 99 beyond a certain point. When the operating'bar is depressed, the short arm of the bell crank moves to the rea-r of the shaft 89 and ermits the bar 98 to move inwardly with 1t, but when the operating bar is raised the rod 100 being forced to the front by the short arm of the bell crank holds the.

bar in a position toward the front where'it will not engage in the spaces 97. This motion is permitted on account of the 'fact that the bar 98 can slide in slots on the two end frames 53. When this bar is in the position vshown in Fig. 5, the keys can be depressed and raised at will, but when the operating bar is lowered the cross-bar will move into the spaces 'which are opposite it and lock all the keys, either in depressed or raised position, according to their condition.

On reference to Fig. 2 it will be noticed that the keys are arranged in several sets, `those shown being sets for registering different columns of gures, with two additional sets, one for4 registering an initial., and the other for registering other matters, as for example, charged, received and paid. The keys are designated according yto the matter that they are intended to register.

I have provided an error-correcting device for each set of keys, whereby if the -wron key is struckand the error is discovered before the manipulation ofthe operating bar 90, it can be corrected merely by striking the right'key. For. this purpose ,(Figs. 5 and 6) I have shown a rod 103 on which are pivoted .a series of lates 104, one plate for each set of keys. provided with a projection 105, and each of the keys isA provided with a projection 106, having a notch 107 adapted to engage the end of the projection 105. All the keys of one section vare soarranged as to permit their notches engaging the projection 105, and it will be seen that when a key is depressed these parts register with each other and the key is held temporarily in depressed position. In depressing the keys suflicently to cause them to be locked in this manner they haveto be forced to a point farther down than that at which the remain after being locked. If the wrong liey is. depressed, the depression of another in the same set will force the plate down to this low point, and willrelease the key already locked, while retaining the key being depressed and locking that when pressure isv removed fr'om it. This provides for the correction' mentioned above, and it also prevents the registering or attempted registering of two figures in the same set of keys.

ach of these plates is for oscillating the rod 109 upon the closing movement of the cash drawer as 'clearly set forth in detail in the hereinbefore mentioned original application. The operating bar is adapted to engage the right-hand p1ate104 when the operatlng bar is depressed. This feature operates in the same manner as the keys. When the operating bar is released by rocking shaft 109 it ascends and carries the cross-bar 98 into an outward or unlocking position. The keys will then fly up on account of the operation of the springs 93,

Aif the bar 98 is out of engagement with the spaces 97, which will be the case-at this time because the operating bar has been raised as described. The keys are therefore in condition to be depressed.

Indz'catz'ng device-The projections 95 on the keys bear upon plates 115 (Figs. 4 and 5). One of these plates is provided for each ofthe sections of keys, and they are preferably pivoted upon a rod 116 whlch is mounted upon a pair of standards 117 constituting a part of the frame. These plates are normally heldl in elevated position by springs 118 bearing upon the shaft 103 or upon any other convenient part of the machine. Located upon a plate 119 above the table are a series of slides 120 normally urged toward the front of the machine by springs 121 (Figs. 4 and 4a). The machine is provided with one of these slides for each section of keys, and each slide carries a standard 122 bearing a plate 123 having a series of teeth 124 upon its front edge as shown in Fig. 5.

acters'to be registered in the set to which the plate belongs. The front tooth represents the first character, as for example zero in a set of numbers, the second 1, and so onto 9. When the plate 115 is in elevated position the first step or tooth is `against it and the machine is in condition The number of teeth isV .equal to the number of figures or other char- 1 and which represents a single step from the zero key. Consequently when a key is depressed and the slide is permitted to move forward by means t'o be described, it will move up to such position that the proper tooth will. engage the projection on the key which is depressed, and this constitutes a limit for its motion. But when no key of any particular set of keys is depressed, the manipulation of the operating bar will not allow the parts connected with that set to move at all, because the first tooth of the plate 123 of that set is in engagement with the rear of the plate 115.

Each slide 120 is provided (Figs. 4 and 6) with a downwardly extending projection 125 which passes .through the plate 119 behind the bar 68. The latter is intended to keep all of the slides 120 in their normal position when the drawer is closed, but when open this bar yields and consequently all the projections 125 are allowed to yield, and are forcedto do so by the springs 121, a. spring 121*1 being employed to operate the slide which is atthe right. Upon moving in this way when the drawer opens, these slides will be stopped at a distance of one or more steps from their original position, according to that key which is depressed. Located adjacent to and above each slide is an indicator carriage 126 (Fig. 4) preferably running on wheels 127 in a direction parallel to that of the motion of the slides. Each carriage is provided with a bottom plate 128 which 'slides upon the top of the plate 119. Therear surfaces of these plates are located in thevpath of the projections 125 corresponding with the same set of keys, consequently as thesev projections are drawn forward with their slides by means of the springs 121 and 121?, they will engage the carriages and move them a distance equal to that which they move themselves. The carriages are impelled toward the rear by springs 1283. Each of these carriages supports a pair of guides 129, each guide being provided with a series of slots 130 equal in number to the number of keysin the set corresponding to that particular carriage. In these slots are guided a corresponding series of' indicator-holders 131. Each of these holders is provided preferably at the top with a casing 132, in which is mounted an indicator 133. These indicators are preferably formed of glass or other transparent material, and the numbers which indicate the transaction to be registered are preferably placed upon the front side, and instead of each number representing the whole number corresponding to that on the key, they are designated in such a manner that the number shown at the front appears in the regular order. In .many cash registers as heretofore constructed the indicator corresponding to a number of two gures, as

Itv will be readily understood that with the mechanism so far described, the position of the indicators is controlled by the keys, and

that there must be a line across the machine.

which will intersect all of the indicator supports which correspond to the keys depressed, or to the zero keys belonging to those sets in which no number is to be registered. This line is the line directly. under the indicator supports of the-zero indicators when the latter are in the normal position, and all that is necessary to do in orderto move the'proper indicators into a more elevated position where they can be seen from the front and back is to place a bar 134 across the machine in a position directly under the original position of the zero indicators, and to raise this bar in such a manner as to elevate all the indicator-holders which are above it and rest upon it. This bar 134 is mounted. upon sliding bars 135 (Figs. 4, 5 and 6) guided to move vertically by guides 136 and by guide-segments 137 meshing with racks 138 on the sliding bars and mounted on a shaft 139. In order to manipulate these parts one of the bars 135 is provided with a projection 140 to which is pivoted aconnecting rod 141 (Fig. 5). This connecting rod is provided with a stud 142 (Fig. 3). This stud projects through a curved slot 143 on the right-hand side plate 53, and its upper surface is inclined so as to form a good seat for a catch 144 which is mounted upon a lever 145. This lever is pivotally mounted upon a lever 146 pivoted at 157 and is normally held in such 'a position as to readily engage the stud 142 by a spring 147. The lever 146 is provided with a stud 148, which if desired may extend through a slotv149 in the side plate so as to receive an o erating spring 150 which normally holds the lever 146 in elevated position and returns it to that position when displaced.` The bar 134 has a stud 151 (Fig. 8) passing through a slot 152 in the left handY side plate 53, and provided with an operating spring 153 for lifting the bar. These parts provide for lifting the bar 134, exposing the indicators which correspond with the keys depressed, and leaving the parts in such position that the catch 144 is free'to engage the stud 142.

The lever 146 is provided with aninclined and elongated slot 15,4 (Fig. 3) through -which passes a projection 155 upon one of the operating levers 88. passes throughv a slot 156 inthe side frame,

and obviously when the operating bar 90 is` depressed it .will act upon the lever 146 through the slot 154 to turn it about its pivot 157, and this operation will cause the stud 142' and consequently the bar 134 to be depressed. Therefore, the depression of the operating bar results Y immediately in the lowering of the indicators which at that time appear in sight, or in other words, the indicators which represent the last sum registered.- The wi hdrawal of the bar 134 below the .bottom of the indicator-holders 131 permits thenr to move with the bars 120 to positions determined-bythe plates 123, and as the drawer slides open 'a tripping linger 158 (Fig.`3) which is moved with the drawer' engages the lower end of the lever 145 and disengages the catch from the stud 142. This permits the spring to elevate the fbar 134 and raises the indicators which correspond to the keys struck. When the operating bar is again raised the lever 146 will be raised with it, and the catch will engage with the stud`142 as before, ready to repeat the operation.

1 59 which is normally forced toward the front of the machine by a spring 160 shown invFig. 3. This plate is provided with a spring or .detent 161 having a head 162,

thereon, provided with -slanting surfaces. A spring 163 engages at the rear'of one of thesel surfaces 1andenormally holds 4the plate vin its position at the rear of the machine, butl as the drawer opens, theca'm surface 7 8 (Fig. 5") engages the lower sidevof the head 162, forces it out ozlreach"I of the spring 163 and permits the spring 160'to pull the whole plate to the"l front, when the drawer' has `reached nearly its outermost position .ex-

posing lthe indicators.- A, This causes the finger 158'to engage with the lever 145. The lever' '145 isv `provided with a spring 164 "against 'which the linger 158 is stopped `as long as the lever is indepre'ssed position.

While the form. of mechanism herein4 shown and vdescribed is admirably adaptedto 'fulfil the objects primarily stated, itis to be understood that-it is not intended toy coniine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in variousy forms, all coming withi n the scope ofthe 1.
